Description

A kind of entity manufacture method based on superthin layer wood plastic composite
Technical field:
The present invention relates to a kind of Product rapid design manufacture method, refer in particular to a kind of entity manufacture method based on superthin layer wood plastic composite.
Technical background:
In manufacturing industry, along with the globalization of economy, market competition is growing more intense, and model change is accelerated, and product is more and more to the future development of multi items, small lot, high accuracy, low cost.
RP technique is born in the U.S. in 1988, expands to rapidly Europe and Japan, and introduces China in the nineties initial stage.Rapid prototyping technology can be divided into two large classes: based on laser technology (laser three-dimensional photoetching, layer separated growth, laser select sintering) with based on microdrop technique (Fused Deposition Modeling, three dimensional printing, entity grinding solidification, heterogeneous jet deposition etc.).
From material aspect, what apply at present is the material that resin, plastics, paper, wax etc. are comparatively easily shaped; But due to the restriction of material, cost and the maintenance cost in these moulding process later stages are high, make it apply and are difficult to further expansion, and rapid forming equipment itself is also very expensive.Therefore the emphasis of RP technique research is research and development and the application thereof of fast shaping material, and goal in research is that research and development are cheap, shrinkage factor is little, have the functional material of mechanical property, color, electric conductivity, corrosion resistance etc. required by different purposes.
China researcher also proposed the raw material using mixtures such as paraffin, water, gypsum as Quick-forming, and achieves effective progress, but does not relate to the method for carrying out rapid shaping based on wood plastic composite.Wood plastic composite is a class advanced composite material (ACM), refers to utilize the main component such as plastics and wood materials, through plastic processings such as extruding, injection mouldings, produces sheet material or section bar.
The present invention is directed to the existing defect of rapid prototyping machine and material, propose a kind of entity manufacture method based on superthin layer wood plastic composite.
Object of the present invention is achieved through the following technical solutions: a kind of entity manufacture method based on superthin layer wood plastic composite, comprises the following steps:
(1) by 3D solid data model that computer aided design cad (Computeraideddesign) software construction will be produced;

(4) layer cross section message composition will be cut and become numerical control NC (Numericalcontrol) procedure;
(5) utilize pulverizer by the mixture of the fibers such as sawdust, rice husk, stalk or several fiber, be ground into particle diameter at the wood fibre of 15 ~ 30 μm;
(6) mix by following mass ratio: 22 ~ 28% polyvinyl chloride, 52% ~ 65% wood fibre, 1.5% ~ 2%TCPP fire retardant, 1% ~ 1.5% Polymer Antistatic Agent, 1.5% ~ 2% compatilizer, 1.5% ~ 3% Glass Fiber Reinforcement, 8% ~ 15% polyvinyl acetate resin adhesive adhesive be made up of the copolymer of rubber and maleic anhydride, obtain wood and mould mixture, the parallel equidirectional two-screw of recycling 50 ~ 100KW power is moulded mixture to wood and is extruded, and obtains wood plastic composite;
(7) wood plastic composite compacting tool set is fixed on moulding press, for the ease of follow-up cutting process, the inner die cavity full-size L of wood plastic composite compacting tool set maxwith cut layer cross section full-size S maxthere is following relation, L max=S max+ (6 ~ 10mm); In order to ensure pressure force and dimensional accuracy, there is following relation, H=d-(0.001 ~ 0.002mm) in the die cavity height H after the upper die and lower die laminating of wood plastic composite compacting tool set and two cut surface spacing d; The wood plastic composite extruded directly fills in square wood plastic composite compacting tool set, waits for after 5 ~ 10 seconds, adopts the four column type moulding press of 50 ~ 100 tons to carry out pressing to wood plastic composite, obtains wood plastic composite thin plate;
(8) according to the NC procedure obtained in step (4), laser cutting machine cuts wood plastic composite thin plate outline, obtains and cuts the consistent wood plastic composite thin plate of layer cross section shape in step (3);
(9) each layer wood plastic composite veneer bonding will processed, is upwards successively superposed by bottom, after obtaining required physical model, is carrying out the processing such as subsequent edges polishing or coating, improves 3D solid machining accuracy and surface quality.
Further improvement of the present invention is: can according to the entity of institute's moulding need add the functional material such as conductive agent, toner, obtain the wood plastic composite with color and electric conductivity.
Further improvement of the present invention is: rolling process can be adopted to obtain wood plastic composite thin plate, the little 0.001 ~ 0.002mm of gap ratio two cut surface spacing d of two pressure rollers.
Adopt the present invention when carrying out Rapid Prototyping processing parts, wood plastic composite need meet following requirement: 1. due to the interface incompatibility of wood powder and resin, the compatilizer and the coupling agent that add appropriate and suitable kind can improve drip molding performance; For varigrained batching, can also play plugs the gap is acted on.2. owing to utilizing the fuel factor of laser cutting machine to cut, so wood plastic composite needs to add quantitative fire retardant.
The present invention compared with prior art has the following advantages: applied widely, cost is low, efficiency is high and forming accuracy is high; Can be applicable to irregular contour, be difficult to the part of Integratively shaping, even closure casing; Can reduce costs and energy consumption, reduce environmental pollution, and this material can be recycled; Owing to being " cascading into shape ", forming speed can be improved; And whole process can realize automatic batch production.
